Using basic inference rules, we can establish the validity of the argument: p ⟹ ¬q, q V r, p V u, ¬r ├ u.

1. We are given the following premises:

  - p ⟹ ¬q (Premise 1)

  - q V r (Premise 2)

  - p V u (Premise 3)

  - ¬r (Premise 4)

2. To prove the conclusion, u, we need to use the premises and apply inference rules.

3. From Premise 4 (¬r) and the Disjunctive Syllogism rule, we can deduce ¬q: (¬r, q V r) ⟹ ¬q.

4. From Premise 1 (p ⟹ ¬q) and Modus Ponens, we can conclude ¬p: (p ⟹ ¬q, ¬q) ⟹ ¬p.

5. From Premise 3 (p V u) and Disjunctive Syllogism, we obtain ¬p V u.

6. Using Disjunctive Syllogism with ¬p V u and ¬p, we can derive u: (¬p V u, ¬p) ⟹ u.

7. From Premise 2 (q V r) and Disjunctive Syllogism, we have q.

8. Finally, using Modus Tollens with q and ¬q, we can deduce ¬p: (q, p ⟹ ¬q) ⟹ ¬p.

9. Therefore, combining ¬p and u, we can conclude the desired result: ¬p ∧ u.

Answer:9.675 because it’s less than 9.70 and 9.75

Step-by-step explanation:

The number of hours on the job, it takes to make $301.55 based on the proportional relationship between the Time in hours and Earnings in dollars is 9.25 hours

A proportional relationship is one in which the ratio of the variables at each point of the dataset is the same or constant.

The possible table in the question obtained from a similar question is presented as follows;

\(\begin{array}{|c|l|} Time\, (hours) &Earnings\, (dollars) \\17 & \$554.20 \\ 20& \$652\\ 22& \$717.20\\\end{bmatrix}\)

The amount earned can be expected to be proportional to the number of hours spent on the job.

Finding the constant of proportionality, k, we get;

554.2/17 = 32.6

652/20 = 32.6

717.20/22 = 32.6

Therefore, the constant of proportionality, k = 32.6

Finding the relationship between the variables graphically

The graph of the Earnings to Time indicates that the relationship between the amount earned to the number of hours used in doing the job is a linear relation.

The slope of the graph of the equation is (717.2 - 554.2)/(22 - 17) = 32.6

The equation of the linear relationship is therefore;

y - 717.2 = 32.6 × (x - 22)

y = 32.6 × (x - 22) + 717.2 = 32.6·x

y = 32.6·x, therefore, the relationship is a proportional relationship

Let t represent the number of hours it takes to make $301.55, we get:

Amount in earnings = 32.6 × Time spent

Therefore;

\(Time \, spent = \dfrac{Amount \, earned}{32.6}\)

When the amount earned = $301.55, we get;

\(Time \, spent = \dfrac{301.55}{32.6} = 9.25\)

The time it takes Natalie to make $301.55 is 9.25 hours

Given an arithmetic series with a first term (a1) and a common difference (d), the formula for the nth term (an) is as follows:

\(a = a1 + (n - 1) * d\)

In this instance, the common difference (d) is 15, and the first term (a1) is 7. When these values are added to the formula, we obtain:

\(a = 7 + (n - 1) * 15\)

Answer: The two numerical expressions that correctly represent the phrase "twice the sum of nine and four" are:

2 * (9 + 4) = 2 * 13 = 26

2(9 + 4) = 2(13) = 26

Both expressions use the correct mathematical operations to represent the phrase "twice the sum of nine and four" and both will yield the same result of 26.

Step-by-step explanation:

Start by finding the side of the square using the perimeter, a square has 4 equal sides. divide the perimeter by 4

now find the area of the square

continue by finding the area of a whole circles using 3 inches as the radius, because 2 of the form a complete circle.

multiply this by 2 to find the area of the 4 circular sections.

Continue by finding the area of the smaller squares, which have a side half of the radius.

since there are 4 multiply by 4

Finally to find the area of the figure we add the area of the bigger square and the circular portions, and substract the area of the smaller squares.

Step-by-step explanation:

The amount of Bruno's yearly pay deducted for FICA is approximately

A. $4,524.15. The closest option provided is A. $4521.15.

To calculate the amount of FICA deducted from Bruno's yearly pay, we need to consider the specific FICA tax rates for Social Security and Medicare.

As of 2021, the Social Security tax rate is 6.2% on income up to a certain threshold, and the Medicare tax rate is 1.45% on all income.

Given that Bruno's gross income per pay period is $4925 and he is paid monthly, we can calculate the yearly gross income as follows:

Yearly gross income = $4925 * 12 = $59,100

To calculate the FICA deduction, we need to find the sum of the Social Security and Medicare taxes. Using the respective tax rates mentioned earlier:

Social Security deduction = $59,100 * 6.2% = $3,667.20

Medicare deduction = $59,100 * 1.45% = $856.95

Adding these two deductions together:

FICA deduction = $3,667.20 + $856.95 = $4,524.15

Therefore, the amount of Bruno's yearly pay deducted for FICA is approximately $4,524.15.

The closest option provided is A. $4521.15.

Therefore, the interest portion of the seventh payment is:7,000 x (1 + r + r2 + r3 + r4 + r5 + r6) / r7 - 7,000.

We have the following payments and their corresponding times of payment:At the end of year 1: $1,000At the end of year 2: $2,000At the end of year 3: $3,000At the end of year 4: $4,000At the end of year 5: $5,000At the end of year 6: $6,000At the end of year 7: $7,000

At the end of year 8: $8,000At the end of year 9: $9,000At the end of year 10: $10,000The present value of these payments is:PMT x [(1 - (1 + r)-n) / r]where PMT is the payment, r is the interest rate per year, and n is the number of years till payment.

For the first payment (end of year 1), the present value is:1,000 x [(1 - (1 + r)-1) / r]which equals

1,000 x (1 - 1 / (1 + r)) / r = 1,000 x ((1 + r - 1) / r) = 1,000

For the second payment (end of year 2), the present value is:2,000 x [(1 - (1 + r)-2) / r]which equals 2,000 x (1 - 1 / (1 + r)2) / r = 2,000 x ((1 + r - 1 / (1 + r)2) / r) = 2,000 x (1 + r) / r2

For the seventh payment (end of year 7), the present value is:

7,000 x [(1 - (1 + r)-7) / r]

which equals

7,000 x (1 - 1 / (1 + r)7) / r = 7,000 x ((1 + r - 1 / (1 + r)7) / r) = 7,000 x (1 + r + r2 + r3 + r4 + r5 + r6) / r7

Answer:

6 packs

Step-by-step explanation:

The answer is 6 packs of tickets. The reasoning behind this is that the graph literally states it. If you go to the side of the graph that shows how much money they spend, and look at 27 you can see that they bought 6 packs of tickets for 27 dollars. If you wanna know how to solve it like mathematically you really wouldn't need to but you can see that if you were to buy 2 packs of tickets it would be 9 dollars (according to the graph) which if we divide 9 by 2 you figure out that for one pack of tickets its $4.50. Then you could easily just divide 27 by 4.5 and you would be left with 6, the answer. Again though u really don't need to do that the graph shows it for you so these questions should be pretty easy. Hope this helped! (also sorry I'm not the best at explaining things but I tried, Goodluck!!) :)

Answer:

The predetermined overhead rate is calculated as follows:

Predetermined overhead rate = Estimated total overhead / Estimated total direct labor hours

In this case, the estimated total overhead is $180,000, and the estimated total direct labor hours are 30,000. Therefore:

Predetermined overhead rate = $180,000 / 30,000 hours

Predetermined overhead rate = $6 per direct labor hour

So, the predetermined overhead rate is $6 per direct labor hour.
